Abstract: Apparatus for rapidly unloading air pressure in an intercooler to atmosphere when a compressor pneumatically connected to the intercooler is unloaded. The apparatus includes a governor pneumatically connected to a reservoir, that, in turn, is connected to receive pressurized air from the air compressor. The governor has a pressure sensing device operable to order unloading of the compressor when air pressure level in the reservoir tank reaches a preset level. An electrically operated valve is pneumatically connected to the intercooler and connected electrically to the pressure sensing device of the governor, with the electrically operated valve being effective to exhaust air pressure in the intercooler when the valve receives an unload signal from the pressure sensing device. The compressor is driven by an electrical motor having one or more speed configurations, with transition occurring between one configuration and another when the compressor is unloaded. The electrically operated valve is effective to unload the intercooler at the time of speed configuration transition to reduce undue motor and electrical contactor heat and thus increase life expectancy of the motor and contactors.

Abstract: A temperature sensor 51 is provided in the bill validator according to the present invention to produce a detection signal when a temperature in the case 11 is lowered below a predetermined level. Upon occurrence of the detection signal of the temperature sensor 51, a first timer starts counting a confirmative period of time. When the first timer counts up the confirmative period of time, a second timer produces a drive signal to activate the conveyer motor 38 for a predetermined warming-up period of time. As the conveyer motor 38 is rotated for warming-up, the belt 23 runs in the case 11 to revive its flexibility and generate heat due to dynamic friction of the mechanic parts including the conveyer motor 38, pulleys 21, 22 and belt 23 during rotation of the conveyer motor 38.

Abstract: A method of responding to overload in a real time control system. Overload is measured through the use of a control parameter such as the occupancy of a control processor or the number of entries in a queue of a module of the system. The overload indication is reduced to one of a plurality of levels. The levels corresponding to a longer term more serious overload are based on control parameter measurements over a longer period of time than the less serious short term overload levels. With autonomous control, each module of the system determines its own overload level and performs overload control actions corresponding to that level. In integrated system overload control, a centralized processor receives overload indications from each of the modules of the system and requests an appropriate overload control action of each module. Advantageously, these arrangements allow the system and its modules to respond to overload more rapidly and to return to normal operation more rapidly.
Patent CA-2251084-C (CA)

IPC: G06F13/40
Filed: 1998-10-21
Granted: 2001-08-07
Abstract: A high-speed data bus utilizes non-contact coupler technology which allows point to multi-point broadcasting of a data signal to multiple sinks at very high (Gb/s) speeds. These point-to-multi-point data bus transmission lines can then be used to construct a higher order multi-point to multi-point data bus, without contention at the bus level, since data can be made to flow continuously along each transmission line. The non-contact technology is implemented as a series of taps on a transmission line; the taps operate by way of capacitive or inductive or directional coupling, which helps to isolate the transmission line from the loading effects of circuitry connected to the taps and permits low distortion and high speed operation. The transmission line may also be terminated in the same slot where it originates, and its outbound section may be etched on a single conductive layer in the backplane or midplane.

Abstract: A method and apparatus for characterizing colloids by suc-cessive measurements of light attenuation or emission of a colloidal mixture at two or more temperatures and at one or more wavelengths. The difference or ratio of the measurements at two or more temper-atures provides a measure of the colloidal stability with respect to temperature. The amount of certain organic colloids that are unsta-ble to temperature variation may be determined from the magnitude of the measurement change. In appropriate mixtures, this method provides a means to distinguish components of colloidal substances based. This method may be specifically applied to determine the sta-bility and concentration of colloidal pitch or wood resin in a pulp or paper process water. In this context it may be used to distinguish colloidal pitch or wood resin from talc, clay, carbon black or other fillers.
